A

Thicker and stronger than the anterior cruciate ligament
Travels from the posterior lateral surface of the medial epicondyle on the fumr to the posterior intercondylar area on the tibia.
Prevents the knee sliding forwards

98
Q

What is the anterior cruciate ligament?

A

Travels from the Intercondylar tibia plateau to the posteriomedial aspect of the lateral femoral condyle

99
Q

What is the medial collateral ligament?

A

Also knwon as the tibial collateral ligament.
Stabilises the knee joint when standing

100
Q

What is the lateral collateral ligament?

A

Also known as the fibular collateral ligament
Maintains knee joint stability through range of motion
Is wider and flatter than the medial collateral ligament.

101
Q

What are the lateral and medial miniscus of the knee?

A

Fibrocartilogenous bands, create 4/5th of a circle.
Widen and deepen the tibial articular surface making it more bowl-shaped to easier fit the femoral condyles, stabilising the joint.
Note the medial meniscus is larger and thicker.

102
Q

What collateral ligament in the knee is the most likely to be injured and why?

A

Tibial collateral ligament.
Most force that injurs a knee comes from the lateral side hence forces the knee to bend medial braking the medial collateral ligament that is located on that side.

103
Q

What meniscus is most likely to be injured and why?

A

The medial miniscus
Is larger in order to fit the larger medial femoral condyle, hence is subject to more friction so the meniscus is more likely to tear or be worn down.

104
Q

What is the knee joint capsule?

A

Surrounds the deep ligaments of the knee.
Is made of an inner synovial membrane and an outer fibrous layer.
Encloses the articular ends of the knee joint.
Provides stability to tendons and ligaments

105
Q

What are bursae?

A

Sac-like structures made of the synovial membrane that protrude through gaps in the fibrous layer of the knee joint capsule
Reduce friction by producing synovial fluid
Can become inflammed

106
Q

What is the function of the oblique popliteal ligament?

A

Prevents hyperextension of the knee

107
Q

What is the function of the anterior ligament of the fibular head?

A
112

Unattached to the capsule so more moveable
Also attached to the popliteus tendon
Muscles around the knee absorb impact
The lateral femoral condyle is smaller
